BUCKLE.

SPECIFICATION forming part of Letters Patent No. 477,947, dated June28,1892. Application filed April 9, 1891. Renewed February 17, 1892.Serial No. 421,809- (No model.)

To all whom it may concern:

Be it known that LlvIAR'rm LOGAN, of the city, county, and State of NewYork, have invented a new and useful Improvement in Buckles, of whichthe followingis a full, clear, and exact description.

This invention relates to buckles for various purposes, uses, orarticles, including suspenders, surcingles, and other belts or straps,or wherever a buckle can ordinarily be used for uniting two pieces orparts together, irrespective of what said parts or pieces are madeof--such as, for instance, woven fabric, cloth, g

manipulating it, also constitutes a locking device, and is representedas composed in part or leather.

Theinvention consists in a buckle of novel construction and in which thetwo leading parts of the buckle-that is, its body and loop piece-aremade to engage after the manner of a clasp, substantially as hereinaftershown and described, and more particularly pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 represents a front view of my improved buckle as applied to asuspender, which is shown only in part. Fig. 2 is a side or longitudinaledge view of the same, and Figs. 3 and 4 are face views of the twoleading parts of the buckle detached from one another. Fig. 5 is apartly sectional front View of a modified construction of the buckleapplied to a surcingle, belt, or strap, such as used for horses; andFig. 6 is a side or longitudinal edge view of the same, the surcingle inboth views only being shown in part.

Referring, in the first instance, to the first four figures of thedrawings, A indicates the one leading part or body of the buckle, and Bthe other leading part or loop-piece thereof, these being the two mainportions, which serve to connect the two divided parts of the strap, or,in other words, the main body C of the suspender and the bifurcated endpiece D of the same.

The body A of the buckle consists in part of a loop-like frame I) inhinged connection with a clamping-bar c, thatin its turn is pivoted ateach end of its clamping face or portion, as at e, to a slide d, as inthe case of other buckles, to provide for adjustment of the buckle onthe body 0 of the suspender to take up or let out the latter, thesuspender portion 0 passing down in between the clamping-bar c, that maybe serrated or toothed, and the slide 01, and being securely held orclamped between the two, excepting when the slide 01 is turned up toliberate the clampingbar a from its hold. The swinging or hinged frameI) of this buckle-body A has a lifter b projecting from its bottom orouter lower margin. This lifter, which may have an attached leather orother tab f for the convenience of has its upper e tremities leftdivided and constructed to form spring-coils 'i, the outer or upperportions of which are extended to constitute spring-arms 70, havingknobs, balls, or projections l on their outer ends,and which the tensionof the sprin -coils i tend to force firmly together, but 'not to lockwith each other, as they move in the same plane and do not cross oneanother. The coils 2' also serve to secure permanent and durableelasticity to the arms 70, carrying the balls Z. Thus constructed, thepart B of the buckle forms a clasp to engage with or over the shank gand cross-bar or cars h of the body part A and serves to hold or lookthe two parts'A and B firmly together and so to unite the oppositepieces of the strap or suspender O and D, it

only being necessary, in order to do so, to

shut down the shank got the lifterb between the balls I Z, which thetension of the suspender will also bring over the cross-bar orprojections h. To release the parts A and B from this look, the lifter bis raised to clear it from engagement with the knobs Z of the clasp.This is easily and quickly done, and the whole contrivance formsastrong, safe, durable, and quickly-operated clasp-buckle.

Figs. 4: and 5 show a modification of the buckle which particularlyadapts. it for surcingles and belts used for securing body-blankets onhorses. Two small cylinders a are pendent from the bar that clamps thesuspender O, and each contains a helical spring d. The arms of the shankg of the lifter are extended and pass up through holes in the bottoms ofthe said cylinders a and also through the spring-coils (1', their upperends being provided with heads that bear on the upper ends of thesprings, as shown. In other respects the construction is the same asbefore described.

Having thus described my invention, what Iclaimas new, and desire tosecure by Letters Patent,.is- V 1. In aclasp-buckle for the purposespecified-,the' combination, with the pendent hinged f ram-ehavinglateral projections h and: a litter at its lower end, of a springclamping-piece for carrying the suspender-ends,the same consisting of acoiled spring whose upper extrem-ities are provided with knobs that areheld pressed inward or towardeaeh other and thus adapted to be sprungover or oit the central shank of the aforesaid frame,fas shown anddescribed.

2. The combination of the bodyA, having ,a loop-frame b, clamping-bar c,slide (1, and

outer or lower shank-like lifter b, constructed substantially asdescribed, and the independent: loop-piece B, constructed to formspringcoils 'i i, the outer or upper portions of which 3 are extended toform arms 70 70, provided with balls or knobs ZZ, arranged to lie in thesame plane and adjacent to each other for engagement with the shank.portion of the lifter b, essentially as herein set forth.

3-. In a clasp-buckle, substantially as herein 5 described, the frameportion b of the bucklebod y A, provided with tubes a, having springs 0'within them, in combination with the lifter I), having side: arms 0',controlled by said springs, and the loop-piece B, having springcoils 'i7 with attached arms is 70,. and balls or knobs Z 1, adapted to engagewith said lifter, as herein set forth.
